statement categorically

Huawei Nandu sent a statement categorically denied the existence of dumping, " we denied media reports said the existence of dumping and Huawei ' access to the Chinese government's illegal subsidies ',solar panel cheap and opposition to the EU launched a media said double-reverse investigation ".
Huawei, Huawei in Europe currently employs more than 7000 employees, indirectly created more than 6000 jobs in Europe, 2011, Huawei local purchase amount of more than 2900000000 dollars.
ZTE said, " we are a global enterprise, has been relying on technological innovation, highly customized products and quality service win the market and customers, there is no illegal government subsidies and dumping. "
In fact, this is not the first to China Telecom equipment manufacturers from the foundation. Two years ago, the EU had on Chinese data card launched anti-dumping and safeguard measures two survey,European Commission months which also relates to Huawei and ZTE two enterprises, but in the end to Belgium wireless network equipment maker O ption from EU withdrawal end.
Thereafter, the European metal workers' Federation ( EM F ) and the European occupation Council ( EW C ) in the telecommunications infrastructure business representatives have united to the European Parliament issued a petition, known as the Chinese enterprises to enter the European market, the competitiveness of enterprises are under serious threat, and Chinese enterprises in Europe, the Middle East and Africa network infrastructure facilities market share in a rising, and Ericsson and other European enterprises share has declined. The representative of China enterprises access to European operators technology transfer concerns.
In Gu Wei looks, the main purpose is to make China's market may be more European enterprises open. It is headquartered in the United States Boston lux research company analysis, China 's current five year plan to build many " smart city ", which means that the 54 item, a total of $153000000000, most of which relates to telecommunications equipment. " No European companies obviously this formal complaints, indicating that they want to get more business in china. "
Huawei, ZTE market in Europe 's main rival has stood out in solidarity with the " Friends of the business ". Ericsson is responsible for government and industry public relations director U LF Pehrsson said the EU, such an approach is not correct, Huawei and ZTE to Ericsson opposition to the EU anti-dumping investigation. And more willing to actively join the EU called for the establishment of a government export financing supporting rules and guidelines for negotiations, UlfPehrsson worries " EU against China company specific behaviors may will trigger a vicious spiral ".
The industry of Huawei, ZTE,opportunity compared with in the European market share, European Nokia Siemens, Al Carter lucent, Ericsson and other enterprises in China to share more. If the central Europe around the outbreak of large-scale communications products trade dispute, both sides will suffer a great loss.

LED street light

LED street light technique characteristics of road lighting objective is to provide a visual night travelers peace firm premise, high brightness LED street lamp, its brightness must fit in the existing road premise,Red meat, fish, eat anti-aging traffic to the brightness of peace to cry.

Currently using universal LED street lamp switch power rectifier filter circuit with ordinary, adjusting circuit, sampling circuit, the flow maintenance circuit and DC constant current output circuit. In the use process of vrla batteries maintenance needs to set up the correct charging and discharging rail system and implemented, talent make the battery to the best function and the use of the longest life expectancy. For every battle of electricity is average peak sunshine is proportional to the real Numbers are, so can have to spring and fall generating capacity and power consumption is fundamental to a balanced, summer power rich; Winter is short. The past a lot investment to solar cells and LED.

For self-discharge, system matching, cost element is not extreme economic and don't share. The light body and the main up system protection of adornment effect, ensure the normal operation cycle. So, try to simplify structure, designed to streamline, in order to reduce the wind resistance, increase the flow velocity of the rain, and pay attention to lose weight, one is to save non-ferrous metal,LED industry grows 2 it is to reduce weight brought about by the stress topic, increase the road lighting of peace.

In high power LED application, heat is another major thinking, at present, the LED in the energy consumption of about 80% above into heat, and semiconductor devices is not high temperature resistant, heat to do bad, get up very serious light failure, some serious half year may has been reduced by half, street in high power LED is much more than one application series, must use aluminum alloy much fin wind) make the radiator.

The new rural construction solar street lamps indispensable recently, rizhao first "new energy use of popular science demonstration village" a phase of the project is expected to finish this month. According to information, DongGangOu razor-nailed town house out, will become the first village rizhao city deputy was "solar village". Main street will also be installed solar street lamps.

Solar street lamps etheric sunshine for energy during the day, charging use at night without complex expensive pipe laying, can adjust the layout of the lamps, the safe and energy-saving free from contamination, as long as the system work mode set run automatically work. In the agricultural produce, rizhao will make for organic, home village, ecological rice industry base, solar installation in the rice field insecticidal lamp.

It is reported, curtilage secco village construction "new energy use of popular science demonstration village",LED system matching design new energy village will be divided into three phases for project construction, a phase of the project will be 120 households, home village every household free installation, a 150 liters value 1800 yuan solar energy water heater, make the whole village solar energy utilization rate of 100%.

SLR camera key words and definitions

ISO is the international standards organization, International Standards Organization. The film was ISO100200and 400kinds, it is speed of different film.
ISO sensitivity is CCD ( or film) on the light sensitive degree. If you use ISO100film camera,2 seconds can be correctly exposed,camera quality will be improved the same light conditions with ISO200film need only seconds to as long as0.5 seconds, using ISO400.
In the digital era, digital camera the main menu have ISO choice,100200400or800, and the film on the same. Look at the type of different, lower to ISO50, the maximum to 25600, digital more sensitive ( the higher sensitivity ).
High ISO is fast but the image coarse particles, not fine to enlarge map. So the landscape photography to use camera minimum sensitivity can get fine pictures. High ISO in general cannot but when it is used.
Shutter
The shutter is the camera exposure time control device. A mechanical shutter, electronic shutter, and the shutter and so on many kinds of electronic mechanical joint.
Aperture
The aperture is adjusted in the light into the lens hole size device. Common aperture value as follows: F1, F1.4, F2, F2.8, F4, F5.6, F8, F11, F16, F22, F32, F44, F64.
The effect of the aperture
The 1hole, which directly affects the image whether the correct exposure, is the key to success;
In 2control of the depth of field, smaller apertures, the greater the depth of field. Although the focal length and the shooting distance all affect the depth of field, but the focal length and object distance change at the same time also affects the composition, if the composition determination, we can control the depth of field of the weapon is only aperture;
The 3aperture effects of picture definition, any one lens are in the medium aperture when imaging the best ( most clearly ), the maximum aperture and minimum aperture time resolution difference.
Exposure
Exposure is the aperture and shutter assembly,Imaging principle by adjusting the size of the aperture and shutter speed, to ensure that the exposure effect.
Focal length
The strict definition is: standard lens is the focal distance is equal to negative ( or CCD ) the length of the diagonal of the lens.
